Xenetic Biosciences, Inc. Reports Fourth Quarter and Full Year 2020 Financial Results

• Driving development of XCART™ platform and leveraging academic collaborations through preclinical development
• Recent clinical, regulatory and commercial advancements from licensing partners leveraging PolyXen® platform technology

FRAMINGHAM, MA / ACCESSWIRE / March 17, 2021 / Xenetic Biosciences, Inc. (NASDAQ:XBIO) (“Xenetic” or the “Company”), a biopharmaceutical company focused on advancing XCART™, a personalized CAR T platform technology engineered to target patient- and tumor-specific neoantigens, today reported its financial results for the fourth quarter and full year 2020, and provided a corporate update.

“Notwithstanding the challenges presented by the COVID-19 pandemic, 2020 was a year of significant progress for the Company, including the establishment of partnerships and academic collaborations and advancement in our development efforts, in particular with respect to CAR design and model cell line development, as well as the strengthening of our financial position. Our focus remains on advancing the XCART™ platform, and we look forward to further evaluation of our XCART™ process in a clinical setting during our upcoming exploratory study in Eastern Europe,” commented Jeffrey Eisenberg, Chief Executive Officer of Xenetic. “Our goal remains to complete our preclinical development phase and advance into a Phase 1 study as quickly as possible.”

XCART Platform Technology Overview: Significantly differentiated, proprietary approach to personalized CAR T therapy targeting tumor specific antigens that are independent of CD19 or other antigens common to all B-Cells. Lead program for Non-Hodgkin lymphomas, an area of significant unmet need, with the potential to address an initial global market opportunity of over $5 billion annually.^[1]

Program Highlights:

• Collaboration with Pharmsynthez and multiple academic institutions in Eastern Europe to optimize the overall XCART™ workflow, including clinical manufacturing processes, and ultimately to conduct a first in-human study in B-cell Non-Hodgkin lymphoma (NHL) patients.
• Research and development collaboration with Scripps Research covering design and implementation of the preclinical development program, as well as method development activities supporting process development for clinical manufacturing.

Upcoming Potential Milestones

• Initiation of exploratory patient biopsy study in Eastern Europe.
• Seeking U.S. FDA INTERACT meeting.
• Initiating process development for clinical CAR T manufacturing.

PolyXen® Platform Technology: Patent-protected platform technology designed for protein or peptide therapeutics, enabling next-generation biological drugs by prolonging a drug’s circulating half-life and potentially improving other pharmacological properties.

Program Highlights:

• Exclusive License Agreement with Takeda Pharmaceuticals Co. Ltd. (“Takeda”) in the field of blood coagulation disorders.
  • Takeda currently has one active development program underway.
  • Royalty payments of approximately $0.4 million received in 2020 as Takeda’s sublicensee has now launched the relevant product in multiple global markets.

• Company’s partner, PJSC Pharmsynthez, announced positive Phase 3 trial results and filed a registration dossier in Russia to obtain approval of Epolong, a polysialylated form of human erythropoietin as a treatment for anemia in patients with chronic kidney disease.

Summary of Financial Results for Fiscal Year 2020

Net loss for the year ended December 31, 2020, was approximately $10.9 million. R&D expenses for the year ended December 31, 2020, were $1.7 million compared to $4.9 million for the year ended December 31, 2019. The decrease was primarily due to IPR&D expense of $3.0 million incurred during the year ended December 31, 2019. General and administrative expenses decreased by approximately $1.3 million, or 28.1% for the year ended December 31, 2020, to $3.4 million from $4.7 million in the comparable period in 2019, primarily due to approximately $1.1 million of transaction costs associated with the XCART™ acquisition incurred during the year ended December 31, 2019. At December 31, 2020, the Company reported working capital was approximately $11.4 million compared to $9.7 million at December 31, 2019. During the year ended December 31, 2020, working capital increased by $1.8 million due to the Company’s December 2020 registered direct common stock offering resulting in approximately $5.4 million in net proceeds. This increase in working capital was substantially offset by the Company’s net loss for the year ended December 31, 2020. The Company ended the year with approximately $11.5 million of cash.
